Problems solved by technology

[0006] However, the above scheme does not have the effect of directly inactivating algae. The above-mentioned single method only limits the nutrients such as nitrogen and phosphorus of algae, and cannot inactivate and remove algae in time, so it needs to be further optimized and improved.

Embodiment 1

[0040] The size of each floating board of the floating bed is 33cm×33cm (9 floating boards / m 2 ), 5cm thick; 2 aquatic plants 2 are planted on each floating board to ensure the number of plants survived. Load aquatic plant 2 with permeable flower pot 6 and cultivate to. Aquatic plants 2 can choose calamus and other plants with well-developed root system, easy survival and suitable for local climate. The floating bed body 1 is fixed to the shore of the water body with some flexible ropes 5, and the diameter of the flexible ropes can be 2-5 cm. In this embodiment, the coverage of the floating bed body 1 is 30%.

[0041] In this embodiment, the insoluble peroxide filler is calcium peroxide filler, and the iron-based adsorption material filler is sponge iron filler. The calcium peroxide filler package and the sponge iron filler package are suspended at intervals at the same time under the floating plate of the floating bed body 1 between the aquatic plants 2, and are evenly dis...

Embodiment 2

[0044] The size of each floating board of the floating bed is 33cm×33cm (9 floating boards / m 2 ), 5cm thick; 2 aquatic plants 2 are planted on each floating board to ensure the number of plants survived. Load aquatic plant 2 with permeable flower pot 6 and cultivate to. Aquatic plants 2 select plants with well-developed root system, such as papaya, easy to survive, and suitable for the local climate. The floating bed body 1 is fixed to the shore of the water body with a number of flexible ropes 5, and the diameter of the flexible ropes is 2-5 cm. In this embodiment, the coverage of the floating bed body 1 is 40%.

[0045] In this embodiment, the insoluble peroxide filler is magnesium peroxide filler, and the iron-based adsorption material filler is iron ore waste filler. The magnesium peroxide filler package and the iron ore waste filler package are suspended at intervals under the floating plate of the floating bed body 1 between the aquatic plants 2, and are evenly distri...

Embodiment 3

[0049] The size of each floating board of the floating bed is 33cm×33cm (9 floating boards / m 2 ), 6cm thick; 2 aquatic plants 2 are planted on each floating board to ensure the number of plants survived. Load aquatic plant 2 with permeable flower pot 6 and cultivate to. Aquatic plants 2 can choose calamus or copper money grass and other plants with well-developed root system, easy to survive, and suitable for the local climate. The floating bed body 1 is fixed to the shore of the water body with some flexible ropes 5, and the diameter of the flexible ropes can be 2-5 cm. In this embodiment, the coverage of the floating bed body 1 is 50%.

[0050] In this embodiment, the insoluble peroxide filler is zinc peroxide filler, and the iron-based adsorption material filler is iron filings filler. The zinc peroxide filler package and the iron filings filler package are hung under the floating bed body 1 floating plate between the aquatic plants 2 at intervals at the same time, and a...

Abstract

The invention discloses a method based on a phosphorus removal and algae removal ecological floating bed and a device thereof, a plurality of floating plates are spliced into a floating bed body, aquatic plants are placed on the floating bed body in an array, and insoluble peroxide filler bags and iron-based adsorption material filler bags are simultaneously suspended under the floating plates of the floating bed body among the aquatic plants at intervals; and the phosphorus and algae removal of the ecological floating bed is realized by controlling the coverage rate of the floating bed body in a water body, controlling the suspension mass ratio of the insoluble peroxide filler to the iron-based adsorption material filler and controlling the total amount of the insoluble peroxide filler and the iron-based adsorption material filler suspended on the floating bed body per square meter. The device is reinforced by the filler, has biological phosphorus removal and physical and chemical phosphorus removal effects, improves the water quality purification efficiency of the floating bed, enables the water ecological environment to be safe and stable, and ensures the phosphorus removal and algae removal effects under the condition of reducing the cost.

Description

technical field [0001] The invention relates to a method and device for controlling eutrophication of landscape water bodies, in particular to a method and device based on an ecological floating bed for phosphorus and algae removal. Background technique [0002] Recycled water replenishment of urban landscape water has been widely used at home and abroad. While the reclaimed water supplies the landscape water, it will bring nitrogen, phosphorus and other exogenous nutrients to the landscape water. Due to the poor self-purification ability and poor mobility of the landscape water, these nutrients will cause eutrophication of the landscape water body, causing the outbreak of algae blooms, resulting in poor viewing, transparency, and damage to the water ecosystem of the scenic lakes and rivers, seriously affecting the scenic lakes and rivers. Features. [0003] In order to solve the eutrophication problem of reclaimed water replenishment landscape water, on the one hand, recl...
